Gummy part of the teeth is denoted by the term advert gingiva. Any inflammation of the gingival is termed as gingival inflammation or gingivitis. The microorganisms can exert its effect on the gingival by releasing some of their toxins. This damage may leads to the access of microorganisms into the deep tissues that can create more damage to the gingival.
The sequence of events that take place during the development of gingivitis can occur in four stages.
Stage I Gingivitis:
It is the initial stage of destruction. Initially there can’t be seen any of the destructive changes except there occurs bleeding when instrument is used to check the health of gingival.
Stage II Gingivitis:
It is known as the early lesion. In this stage the changes are more than that were seen in the first stage but these are not more severe. You can see the reddish hue in the gingival as the fibroblasts cells that are responsible for the red blood cell formation shows more damaging changes.
Also the bleeding while probing a little may become more evident.
Stage III Gingivitis:
It is also known as the established lesions as the changes got more severe and till now they get more established.
The bluish hue on the reddened gingival due to impaired blood flow can be seen.
The inflammation on the gingival can be seen from moderately to intensely severe.
Stage IV Gingivitis:
It is the advanced lesion and it is also known as phase of advanced breakdown of total tissue surrounding the teeth.
The gingival become erythematous and due to loss of junctional epithelium at the junction of gingiva and the tooth surface, there got some space created called pockets which becomes the house of micro-organisms and also the food got stuck there on which these microorganisms feed their selves.
At this stage having all the features of previous stages there also occur some itching sensations to the person where pockets are present and the relief is got only when some sharp thing is placed between the teeth and there occurs some bleeding.
